Modulation sources for analog modulation
Internal modulation generator
Shape

Frequency range
0.1 Hz to 1 MHz
Resolution of setting
0.1 Hz
Frequency uncertainty
< 0.001 Hz + relative deviation of
reference frequency
Multifunction generator (R&S
®
SMW-K24 option)
If two RF paths are installed (signal paths A and B), the multifunction generator can be used either on signal path A or B with one
R&S
®
SMW-K24 option. For the multifunction generator to be used on signal paths A and B simultaneously, two R&S
®
SMW-K24 must
be installed.
The R&S
®
SMW-K24 multifunction generator option consists of three function generators that can be set independently. Two of the
three signal sources can be added with different weighting. The total voltage is limited by the maximum output voltage.
